Description:

time listener

time_listener #

An extremely easy-to-use flutter plugin that allows you to listen time changes.
Features #
This package makes very easy to listen time changes using a stream.
The code responsible for checking time diff is run in an isolate, so you don't have to worry about performance.
Usage #
To start listening create instance of the class and call "listen" method on it.
Stream event with the new date will come every second.
// actively listen for time updates with the interval specified in parameter
// until listener.cancel() is called
final listener = TimeListener()..listen((DateTime dt) {
print('${dt.hour}:${dt.minute}:${dt.second}');
});

// don't forget to cancel listener when it is no longer needed
// so the program doesn't run forever
await listener.cancel();

To specify interval (by default every minute) you can use custom factory.

// below code will emit new DateTime every minute without seconds precision
// output - 21:37:00
final listener = TimeListener()..listen((DateTime dt) {
print('${dt.hour}:${dt.minute}:${dt.second}');
});

// but if you need u can specify more precise interval with custom factory
// output - 21:37:24
final listener = TimeListener.create(interval: CheckInterval.seconds)..listen((DateTime dt) {
print('${dt.hour}:${dt.minute}:${dt.second}');
});
